Top 10 SMT Machine Manufacturers in 2024

Surface mount technology (SMT) has transformed electronics manufacturing in recent decades. SMT mounts components directly on the PCB surface without through holes. This allows smaller and more automated assembly.

SMT placement machines accurately pick surface mount components from reels or trays using vacuum nozzles and precisely place them onto PCBs at high speeds.

Companies across consumer electronics, automotive, aerospace, medical, and other industries rely on these machines to assemble their PCBs.

One such company is PCBMay, one of China’s largest PCB manufacturers. By leveraging high-end SMT lines, PCBMay can produce boards for everything from smartphones to industrial equipment.

What is SMT?

Surface mount technology (SMT) attaches components directly to the PCB surface instead of through holes. SMT components have metal pads that solder to matching pads on the PCB.

SMT allows smaller and lighter products. It packs components densely on both sides of PCBs without holes. SMT works with automated assembly like pick-and-place machines. Components come on tapes and reels for easy handling.

SMT accommodates microelectronics as traditional insert mounts were unsuitable for tiny surface mount chips. High-volume consumer electronics rely predominantly on SMT today.

However, SMT does have some disadvantages.

It makes repairs and modifications harder compared to through-hole PCBs. The solder joint stresses can also impact reliability. Proper design and assembly process control is critical. Thermal management is an important consideration due to higher density.

Overall, the benefits of miniaturization and automation provided by SMT have made it the assembly method of choice for modern electronics.

Overview of SMT Placement Machines

SMT placement machines, also known as pick-and-place machines or mounters, are automated systems used to place surface mount components onto PCBs during electronics manufacturing. They are key equipment in any SMT assembly line.

Modern SMT pick-and-place machines utilize advanced techniques to achieve extremely fast and accurate component placement. They use computer vision with cameras and lasers to precisely locate board fiducials and component pads.

Precision robotic motion control enables the pick-and-place heads to move components from feeders to PCBs with accuracies reaching 0.02mm. Multiple heads allow simultaneous multi-site placement, drastically reducing assembly times.

Feeders containing taped components are loaded onto large-capacity racks. Tape widths range from 8mm to 56mm. Solenoid or vacuum nozzles on the placement heads pick components and place them on the solder paste-coated pads on the PCBs.

On-head or in-line metrology verifies component placement accuracy. High-end flexible machines can handle component sizes from 0.4mm chips up to 55mm x 80mm odd-forms. Speeds exceed 100,000 components per hour.

PCB support systems hold boards firmly during assembly. Conveyor ovens reflow the solder paste after population. The entire assembly process is optimized through software that integrates CAD data, component libraries, pick-and-place sequences, and inspection parameters.

By automating high-precision surface mount assembly, SMT placement machines enable mass production of electronic products with shorter time-to-market and lower costs.

Types of SMT machines

There are several types of SMT placement machines designed for different production needs:

Pick-and-Place Machines

Pick-and-place machines are the most common type of SMT mounter. They use automatic pick-up heads to take components from feeders and accurately place them onto PCBs. The main types include:

High-speed mounters: For very fast component placement. Multi-head for production volumes over 30,000 boards/day.

Flexible placement machines: Handle a wide range of components. Exchangeable heads for optimal speeds.

Dual delivery mounters: Improve flexibility using two feeders per component.

Odd-form placers: For large, heavy, and fragile components.

Chip shooters: High-speed mounting of tiny chip components.

Stencil Printers

Stencil printers use a metal stencil to apply a precise pattern of solder paste onto the PCB pads. This is a preparatory step before surface mount placement.

Stencils are laser-cut for each unique PCB design. Stencil printers optimize paste dispensing and board support for consistent printing across entire production batches.

Speed, accuracy, flexibility, and reliability are key specs to consider when selecting SMT placement machines. The type of mounter must align with production volumes and product complexity.

Reflow Ovens

Reflow ovens use precisely controlled heating zones to form solder joints by reflowing the solder paste deposited during printing. Infrared, convection, or vapor phase heating is used. Profiles are optimized to ensure even heating without damaging components.

Wave Soldering Machines

Used for soldering through-hole component leads and bottom-side SMT components in a single pass. A wave of molten solder in the machine forms solder joints with the underside of boards as they pass over it.

Nitrogen blanketing prevents oxidation. Ideal for high-volume double-sided PCB production.

SMT Machine Calibration and Maintenance

Proper calibration and preventive maintenance are crucial for keeping SMT placement machines, printers, and reflow ovens running at optimal performance and accuracy.

Here are key aspects:

Routine maintenance schedules must be established and followed. Typical schedules range from daily to monthly tasks.

Daily procedures include visual inspections, cleanliness checks, wipe-downs, and feeder/nozzle checks.

Pick-and-place mounters require extensive calibration to maintain precision placement accuracy. Vision system calibration verifies camera focus, magnification, and alignment.

Nozzle tip calibration ensures consistent pick and place heights. Feeder position calibration is also critical.

On mounters, XY motion systems must be calibrated periodically to account for positional errors caused by repeatable mechanical inaccuracies over time. This involves using calibration kits with reference PCBs and software adjustment of placement programs.

Stencil printers require regular inspection and cleaning between prints to maintain printing consistency and avoid clogging or damage. The stencils themselves need cleaning and inspection for any perforation defects or clogged apertures.

Reflow ovens require careful thermocouple calibration and profiling to ensure thermal uniformity over time. Conveyors and mechanisms should be inspected and lubricated. Filters and heaters need cleaning.

Maintenance tasks should only be performed by qualified technicians following safety procedures outlined by OEMs. Machine downtime should be minimized.

Data from calibrations, diagnostics, and inspections help predict problems before failures occur. Well-maintained machines are essential for maximizing SMT quality and throughput.
